Achievement Stories

We at MARCH PUMPEN are able to pump even the most difficult liquids due to our versatile range of pumps. A small selection of possible applications is shown in the following list. This list will be continuously extended by us and our customers in the future.

TEF-MAG® 201 for neutralization systems

A beautiful sight!
We are currently shipping 22 pieces of non-metallic gear pumps TEF-MAG® 201 made of PP with NEMA56C motor adapter for a customer in Canada. These are used there in neutralization systems in waste water treatment. Various acids and bases are pumped to neutralize the waste water. The operating point is around 50 l/h at a differential pressure of 5 bar. These pumps are specially designed for the roughest applications and also for aggressive acids and alkalis.

VANE-MAG® MPA for SNCR plants

Application category:

Environmental technology, flue gas cleaning, flue gas denitrification


Selective non-catalytic reduction of nitrogen oxides (SNCR process)

Suitable pump type:

MPA, magnetically driven rotary sliding vane pump

SNCR systems reduce the nitrogen oxides produced during combustion processes. SNCR systems can be found in incineration or firing systems such as:

  • Waste incinerators
  • Incinerators for wood or biomass
  • Oil and coal fired boiler plants
  • Power plant operations
  • Rotary kilns for cement and lime
  • Liquid waste, e.g. solvents

SNCR plants are typically operated with an aqueous urea solution or ammonia water as the reducing medium. This reducing medium reacts with the environmentally harmful nitrogen oxides (NOx) to form environmentally harmless nitrogen (N2) and water.

To inject the reducing medium into the incinerator, a differential pressure of up to 10 bar is required. The feed volume depends on the size of the incineration plant, typically, a volume flow between 100 l/h and 1000 l/h is required. When using ammonia water, it is recommended to aim for a low engine speed in order to reduce the NPSHR and prevent cavitation. It depends on the respective plant manufacturer whether the pumps are operated with frequency converters or overflow valves in order to dose the required amount into the incineration chamber.
